Import bind-9.16.20
--- 9.16.20 released ---
5689. [security] An assertion failure occurred when named attempted to
send a UDP packet that exceeded the MTU size, if
Response Rate Limiting (RRL) was enabled.
(CVE-2021-25218) [GL #2856]
5688. [bug] Zones using KASP and inline-signed zones failed to apply
changes from the unsigned zone to the signed zone under
certain circumstances. This has been fixed. [GL #2735]
5687. [bug] "rndc reload <zonename>" could trigger a redundant
reload for an inline-signed zone whose zone file was not
modified since the last "rndc reload". This has been
fixed. [GL #2855]
5686. [func] The number of internal data structures allocated for
each zone was reduced. [GL #2829]
5685. [bug] named failed to check the opcode of responses when
performing zone refreshes, stub zone updates, and UPDATE
forwarding. This has been fixed. [GL #2762]
5682. [bug] Some changes to "zone-statistics" settings were not
properly processed by "rndc reconfig". This has been
fixed. [GL #2820]
5681. [func] Relax the checks in the dns_zone_cdscheck() function to
allow CDS and CDNSKEY records in the zone that do not
match an existing DNSKEY record, as long as the
algorithm matches. This allows a clean rollover from one
provider to another in a multi-signer DNSSEC
configuration. [GL #2710]
5679. [func] Thread affinity is no longer set. [GL #2822]
5678. [bug] The "check DS" code failed to release all resources upon
named shutdown when a refresh was in progress. This has
been fixed. [GL #2811]
5672. [bug] Authentication of rndc messages could fail if a
"controls" statement was configured with multiple key
algorithms for the same listener. This has been fixed.
[GL #2756]
--- 9.16.19 released ---
5671. [bug] A race condition could occur where two threads were
competing for the same set of key file locks, leading to
a deadlock. This has been fixed. [GL #2786]
5670. [bug] create_keydata() created an invalid placeholder keydata
record upon a refresh failure, which prevented the
database of managed keys from subsequently being read
back. This has been fixed. [GL #2686]
5669. [func] KASP support was extended with the "check DS" feature.
Zones with "dnssec-policy" and "parental-agents"
configured now check for DS presence and can perform
automatic KSK rollovers. [GL #1126]
5668. [bug] Rescheduling a setnsec3param() task when a zone failed
to load on startup caused a hang on shutdown. This has
been fixed. [GL #2791]
5667. [bug] The configuration-checking code failed to account for
the inheritance rules of the "dnssec-policy" option.
This has been fixed. [GL #2780]
5666. [doc] The safe "edns-udp-size" value was tweaked to match the
probing value from BIND 9.16 for better compatibility.
[GL #2183]
5665. [bug] If nsupdate sends an SOA request and receives a REFUSED
response, it now fails over to the next available
server. [GL #2758]
5664. [func] For UDP messages larger than the path MTU, named now
sends an empty response with the TC (TrunCated) bit set.
In addition, setting the DF (Don't Fragment) flag on
outgoing UDP sockets was re-enabled. [GL #2790]
5662. [bug] Views with recursion disabled are now configured with a
default cache size of 2 MB unless "max-cache-size" is
explicitly set. This prevents cache RBT hash tables from
being needlessly preallocated for such views. [GL #2777]
5661. [bug] Change 5644 inadvertently introduced a deadlock: when
locking the key file mutex for each zone structure in a
different view, the "in-view" logic was not considered.
This has been fixed. [GL #2783]
5658. [bug] Increasing "max-cache-size" for a running named instance
(using "rndc reconfig") did not cause the hash tables
used by cache databases to be grown accordingly. This
has been fixed. [GL #2770]
5655. [bug] Signed, insecure delegation responses prepared by named
either lacked the necessary NSEC records or contained
duplicate NSEC records when both wildcard expansion and
CNAME chaining were required to prepare the response.
This has been fixed. [GL #2759]
5653. [bug] A bug that caused the NSEC3 salt to be changed on every
restart for zones using KASP has been fixed. [GL #2725]
--- 9.16.18 released ---
5660. [bug] The configuration-checking code failed to account for
the inheritance rules of the "key-directory" option.
[GL #2778]
5659. [bug] When preparing DNS responses, named could replace the
letters 'W' (uppercase) and 'w' (lowercase) with '\000'.
This has been fixed. [GL #2779]
--- 9.16.17 released ---
5652. [bug] A copy-and-paste error in change 5584 caused the
IP_DONTFRAG socket option to be enabled instead of
disabled. This has been fixed. [GL #2746]
5651. [func] Refactor zone dumping to be processed asynchronously via
the uv_work_t thread pool API. [GL #2732]
5650. [bug] Prevent a crash that could occur if serve-stale was
enabled and a prefetch was triggered during a query
restart. [GL #2733]
5649. [bug] If a query was answered with stale data on a server with
DNS64 enabled, an assertion could occur if a non-stale
answer arrived afterward. [GL #2731]
5648. [bug] The calculation of the estimated IXFR transaction size
in dns_journal_iter_init() was invalid. [GL #2685]
5644. [bug] Fix a race condition in reading and writing key files
for zones using KASP and configured in multiple views.
[GL #1875]
5643. [cleanup] "make install" no longer creates an empty
${localstatedir}/run directory. [GL #2709]
5642. [bug] Zones which are configured in multiple views with
different values set for "dnssec-policy" and with
identical values set for "key-directory" are now
detected and treated as a configuration error.
[GL #2463]
5641. [bug] Address a potential memory leak in
dst_key_fromnamedfile(). [GL #2689]
5639. [bug] Check that the first and last SOA record of an AXFR are
consistent. [GL #2528]
5638. [bug] Improvements related to network manager/task manager
integration:
- isc_managers_create() and isc_managers_destroy()
functions were added to handle setup and teardown of
netmgr, taskmgr, timermgr, and socketmgr, since these
require a precise order of operations now.
- Event queue processing is now quantized to prevent
infinite looping.
- The netmgr can now be paused from within a netmgr
thread.
- Deadlocks due to a conflict between netmgr's
pause/resume and listen/stoplistening operations were
fixed.
[GL #2654]
5633. [doc] The "inline-signing" option was incorrectly described as
being inherited from the "options"/"view" levels and was
incorrectly accepted at those levels without effect.
This has been fixed. [GL #2536]
5624. [func] Task manager events are now processed inside network
manager loops. The task manager no longer needs its own
set of worker threads, which improves resolver
performance. [GL #2638]
--- 9.16.16 released ---
5637. [func] Change the default value of the "max-ixfr-ratio" option
to "unlimited". [GL #2671]
5636. [bug] named and named-checkconf did not report an error when
multiple zones with the "dnssec-policy" option set were
using the same zone file. This has been fixed.
[GL #2603]
5635. [bug] Journal compaction could fail when a journal with
invalid transaction headers was not detected at startup.
This has been fixed. [GL #2670]
5634. [bug] If "dnssec-policy" was active and a private key file was
temporarily offline during a rekey event, named could
incorrectly introduce replacement keys and break a
signed zone. This has been fixed. [GL #2596]
5633. [doc] The "inline-signing" option was incorrectly described as
being inherited from the "options"/"view" levels and was
incorrectly accepted at those levels without effect.
This has been fixed. [GL #2536]
5632. [func] Add a new built-in KASP, "insecure", which is used to
transition a zone from a signed to an unsigned state.
The existing built-in KASP "none" should no longer be
used to unsign a zone. [GL #2645]
5631. [protocol] Update the implementation of the ZONEMD RR type to match
RFC 8976. [GL #2658]
5630. [func] Treat DNSSEC responses containing NSEC3 records with
iteration counts greater than 150 as insecure.
[GL #2445]
5629. [func] Reduce the maximum supported number of NSEC3 iterations
that can be configured for a zone to 150. [GL #2642]
5627. [bug] RRSIG(SOA) RRsets placed anywhere other than at the zone
apex were triggering infinite resigning loops. This has
been fixed. [GL #2650]
5626. [bug] When generating zone signing keys, KASP now also checks
for key ID conflicts among newly created keys, rather
than just between new and existing ones. [GL #2628]
5625. [bug] A deadlock could occur when multiple "rndc addzone",
"rndc delzone", and/or "rndc modzone" commands were
invoked simultaneously for different zones. This has
been fixed. [GL #2626]
5622. [cleanup] The lib/samples/ directory has been removed, as export
versions of libraries are no longer maintained.
[GL !4835]
5619. [protocol] Implement draft-vandijk-dnsop-nsec-ttl, updating the
protocol such that NSEC(3) TTL values are set to the
minimum of the SOA MINIMUM value or the SOA TTL.
[GL #2347]
5618. [bug] Change 5149 introduced some inconsistencies in the way
record TTLs were presented in cache dumps. These
inconsistencies have been eliminated. [GL #389]
[GL #2289]
--- 9.16.12 released ---
5578. [protocol] Make "check-names" accept A records below "_spf",
"_spf_rate", and "_spf_verify" labels in order to cater
for the "exists" SPF mechanism specified in RFC 7208
section 5.7 and appendix D.1. [GL #2377]
5577. [bug] Fix the "three is a crowd" key rollover bug in KASP by
correctly implementing Equation (2) of the "Flexible and
Robust Key Rollover" paper. [GL #2375]
5575. [bug] When migrating to KASP, BIND 9 considered keys with the
"Inactive" and/or "Delete" timing metadata to be
possible active keys. This has been fixed. [GL #2406]
5572. [bug] Address potential double free in generatexml().
[GL #2420]
5571. [bug] named failed to start when its configuration included a
zone with a non-builtin "allow-update" ACL attached.
[GL #2413]
5570. [bug] Improve performance of the DNSSEC verification code by
reducing the number of repeated calls to
dns_dnssec_keyfromrdata(). [GL #2073]
5569. [bug] Emit useful error message when "rndc retransfer" is
applied to a zone of inappropriate type. [GL #2342]
5568. [bug] Fixed a crash in "dnssec-keyfromlabel" when using ECDSA
keys. [GL #2178]
5567. [bug] Dig now reports unknown dash options while pre-parsing
the options. This prevents "-multi" instead of "+multi"
from reporting memory usage before ending option parsing
with "Invalid option: -lti". [GL #2403]
5566. [func] Add "stale-answer-client-timeout" option, which is the
amount of time a recursive resolver waits before
attempting to answer the query using stale data from
cache. [GL #2247]
5565. [func] The SONAMEs for BIND 9 libraries now include the current
BIND 9 version number, in an effort to tightly couple
internal libraries with a specific release. [GL #2387]
5562. [security] Fix off-by-one bug in ISC SPNEGO implementation.
(CVE-2020-8625) [GL #2354]
5561. [bug] KASP incorrectly set signature validity to the value of
the DNSKEY signature validity. This is now fixed.
[GL #2383]
5560. [func] The default value of "max-stale-ttl" has been changed
from 12 hours to 1 day and the default value of
"stale-answer-ttl" has been changed from 1 second to 30
seconds, following RFC 8767 recommendations. [GL #2248]
5456. [func] Added "primaries" as a synonym for "masters" in
named.conf, and "primary-only" as a synonym for
"master-only" in the parameters to "notify", to bring
terminology up-to-date with RFC 8499. [GL #1948]
5362. [func] Limit the size of IXFR responses so that AXFR will
be used instead if it would be smaller. This is
controlled by the "max-ixfr-ratio" option, which
is a percentage representing the ratio of IXFR size
to the size of the entire zone. This value cannot
exceed 100%, which is the default. [GL #1515]
--- 9.16.11 released ---
5559. [bug] The --with-maxminddb=PATH form of the build-time option
enabling support for libmaxminddb was not working
correctly. This has been fixed. [GL #2366]
5557. [bug] Prevent RBTDB instances from being destroyed by multiple
threads at the same time. [GL #2317]
5556. [bug] Further tweak newline printing in dnssec-signzone and
dnssec-verify. [GL #2359]
5555. [bug] server->reload_status was not properly initialized.
[GL #2361]
5554. [bug] dnssec-signzone and dnssec-verify were missing newlines
between log messages. [GL #2359]
5553. [bug] When reconfiguring named, removing "auto-dnssec" did not
turn off DNSSEC maintenance. [GL #2341]
5552. [func] When switching to "dnssec-policy none;", named now
permits a safe transition to insecure mode and publishes
the CDS and CDNSKEY DELETE records, as described in RFC
8078. [GL #1750]
5551. [bug] named no longer attempts to assign threads to CPUs
outside the CPU affinity set. Thanks to Ole Bjørn
Hessen. [GL #2245]
5550. [func] dnssec-signzone and named now log a warning when falling
back to the "increment" SOA serial method. [GL #2058]
5545. [func] OS support for load-balanced sockets is no longer
required to receive incoming queries in multiple netmgr
threads. [GL #2137]
5543. [bug] Fix UDP performance issues caused by making netmgr
callbacks asynchronous-only. [GL #2320]
5542. [bug] Refactor netmgr. [GL #1920] [GL #2034] [GL #2061]
[GL #2194] [GL #2221] [GL #2266] [GL #2283] [GL #2318]
[GL #2321]
--- 9.16.10 released ---
5544. [func] Restore the default value of "nocookie-udp-size" to 4096
bytes. [GL #2250]
5541. [func] Adjust the "max-recursion-queries" default from 75 to
100. [GL #2305]
5540. [port] Fix building with native PKCS#11 support for AEP Keyper.
[GL #2315]
5539. [bug] Tighten handling of missing DNS COOKIE responses over
UDP by falling back to TCP. [GL #2275]
5538. [func] Add NSEC3 support to KASP. A new option for
"dnssec-policy", "nsec3param", can be used to set the
desired NSEC3 parameters. NSEC3 salt collisions are
automatically prevented during resalting. Salt
generation is now logged with zone context. [GL #1620]
5534. [bug] The CNAME synthesized from a DNAME was incorrectly
followed when the QTYPE was CNAME or ANY. [GL #2280]
--- 9.16.9 released ---
5533. [func] Add the "stale-refresh-time" option, a time window that
starts after a failed lookup, during which a stale RRset
is served directly from cache before a new attempt to
refresh it is made. [GL #2066]
5530. [bug] dnstap did not capture responses to forwarded UPDATE
requests. [GL #2252]
5527. [bug] A NULL pointer dereference occurred when creating an NTA
recheck query failed. [GL #2244]
5525. [bug] Change 5503 inadvertently broke cross-compilation by
replacing a call to AC_LINK_IFELSE() with a call to
AC_RUN_IFELSE() in configure.ac. This has been fixed,
making cross-compilation possible again. [GL #2237]
5523. [bug] The initial lookup in a zone transitioning to/from a
signed state could fail if the DNSKEY RRset was not
found. [GL #2236]
5522. [bug] Fixed a race/NULL dereference in TCPDNS send. [GL #2227]
5520. [bug] Fixed a number of shutdown races, reference counting
errors, and spurious log messages that could occur
in the network manager. [GL #2221]
5518. [bug] Stub zones now work correctly with primary servers using
"minimal-responses yes". [GL #1736]
5517. [bug] Do not treat UV_EOF as a TCP4RecvErr or a TCP6RecvErr.
[GL #2208]
--- 9.16.8 released ---
5516. [func] The default EDNS buffer size has been changed from 4096
to 1232 bytes. [GL #2183]
5515. [func] Add 'rndc dnssec -rollover' command to trigger a manual
rollover for a specific key. [GL #1749]
5514. [bug] Fix KASP expected key size for Ed25519 and Ed448.
[GL #2171]
5513. [doc] The ARM section describing the "rrset-order" statement
was rewritten to make it unambiguous and up-to-date with
the source code. [GL #2139]
5512. [bug] "rrset-order" rules using "order none" were causing
named to crash despite named-checkconf treating them as
valid. [GL #2139]
5511. [bug] 'dig -u +yaml' failed to display timestamps to the
microsecond. [GL #2190]
5510. [bug] Implement the attach/detach semantics for dns_message_t
to fix a data race in accessing an already-destroyed
fctx->rmessage. [GL #2124]
5509. [bug] filter-aaaa: named crashed upon shutdown if it was in
the process of recursing for A RRsets. [GL #1040]
5508. [func] Added new parameter "-expired" for "rndc dumpdb" that
also prints expired RRsets (awaiting cleanup) to the
dump file. [GL #1870]
5507. [bug] Named could compute incorrect SIG(0) responses.
[GL #2109]
5506. [bug] Properly handle failed sysconf() calls, so we don't
report invalid memory size. [GL #2166]
5505. [bug] Updating contents of a mixed-case RPZ could cause some
rules to be ignored. [GL #2169]
5503. [bug] Cleaned up reference counting of network manager
handles, now using isc_nmhandle_attach() and _detach()
instead of _ref() and _unref(). [GL #2122]
--- 9.16.7 released ---
5501. [func] Log CDS/CDNSKEY publication. [GL #1748]
5500. [bug] Fix (non-)publication of CDS and CDNSKEY records.
[GL #2103]
5499. [func] Add '-P ds' and '-D ds' arguments to dnssec-settime.
[GL #1748]
5497. [bug] 'dig +bufsize=0' failed to disable EDNS. [GL #2054]
5496. [bug] Address a TSAN report by ensuring each rate limiter
object holds a reference to its task. [GL #2081]
5495. [bug] With query minimization enabled, named failed to
resolve ip6.arpa. names that had extra labels to the
left of the IPv6 part. [GL #1847]
5494. [bug] Silence the EPROTO syslog message on older systems.
[GL #1928]
5493. [bug] Fix off-by-one error when calculating new hash table
size. [GL #2104]
5492. [bug] Tighten LOC parsing to reject a period (".") and/or "m"
as a value. Fix handling of negative altitudes which are
not whole meters. [GL #2074]
5491. [bug] rbtversion->glue_table_size could be read without the
appropriate lock being held. [GL #2080]
5489. [bug] Named erroneously accepted certain invalid resource
records that were incorrectly processed after
subsequently being written to disk and loaded back, as
the wire format differed. Such records include: CERT,
IPSECKEY, NSEC3, NSEC3PARAM, NXT, SIG, TLSA, WKS, and
X25. [GL !3953]
5488. [bug] NTA code needed to have a weak reference on its
associated view to prevent the latter from being deleted
while NTA tests were being performed. [GL #2067]
5486. [func] Add 'rndc dnssec -checkds' command, which signals to
named that the DS record for a given zone or key has
been updated in the parent zone. [GL #1613]
--- 9.16.6 released ---
5484. [func] Expire zero TTL records quickly rather than using them
for stale answers. [GL #1829]
5483. [func] A new configuration option "stale-cache-enable" has been
introduced to enable or disable keeping stale answers in
cache. [GL #1712]
5482. [bug] If the Duplicate Address Detection (DAD) mechanism had
not yet finished after adding a new IPv6 address to the
system, BIND 9 would fail to bind to IPv6 addresses in a
tentative state. [GL #2038]
5481. [security] "update-policy" rules of type "subdomain" were
incorrectly treated as "zonesub" rules, which allowed
keys used in "subdomain" rules to update names outside
of the specified subdomains. The problem was fixed by
making sure "subdomain" rules are again processed as
described in the ARM. (CVE-2020-8624) [GL #2055]
5480. [security] When BIND 9 was compiled with native PKCS#11 support, it
was possible to trigger an assertion failure in code
determining the number of bits in the PKCS#11 RSA public
key with a specially crafted packet. (CVE-2020-8623)
[GL #2037]
5479. [security] named could crash in certain query resolution scenarios
where QNAME minimization and forwarding were both
enabled. (CVE-2020-8621) [GL #1997]
5478. [security] It was possible to trigger an assertion failure by
sending a specially crafted large TCP DNS message.
(CVE-2020-8620) [GL #1996]
5477. [bug] The idle timeout for connected TCP sockets, which was
previously set to a high fixed value, is now derived
from the client query processing timeout configured for
a resolver. [GL #2024]
5476. [security] It was possible to trigger an assertion failure when
verifying the response to a TSIG-signed request.
(CVE-2020-8622) [GL #2028]
5475. [bug] Wildcard RPZ passthru rules could incorrectly be
overridden by other rules that were loaded from RPZ
zones which appeared later in the "response-policy"
statement. This has been fixed. [GL #1619]
5474. [bug] dns_rdata_hip_next() failed to return ISC_R_NOMORE
when it should have. [GL !3880]
5473. [func] The RBT hash table implementation has been changed
to use a faster hash function (HalfSipHash2-4) and
Fibonacci hashing for better distribution. Setting
"max-cache-size" now preallocates a fixed-size hash
table so that rehashing does not cause resolution
brownouts while the hash table is grown. [GL #1775]
5471. [bug] The introduction of KASP support inadvertently caused
the second field of "sig-validity-interval" to always be
calculated in hours, even in cases when it should have
been calculated in days. This has been fixed. (Thanks to
Tony Finch.) [GL !3735]
5469. [port] On illumos, a constant called SEC is already defined in
<sys/time.h>, which conflicts with an identically named
constant in libbind9. This conflict has been resolved.
[GL #1993]
5468. [bug] Addressed potential double unlock in process_fd().
[GL #2005]
5466. [bug] Addressed an error in recursive clients stats reporting.
[GL #1719]
5465. [func] Added fallback to built-in trust-anchors, managed-keys,
or trusted-keys if the bindkeys-file (bind.keys) cannot
be parsed. [GL #1235]
5464. [bug] Requesting more than 128 files to be saved when rolling
dnstap log files caused a buffer overflow. This has been
fixed. [GL #1989]
5462. [bug] Move LMDB locking from LMDB itself to named. [GL #1976]
5461. [bug] The STALE rdataset header attribute was updated while
the write lock was not being held, leading to incorrect
statistics. The header attributes are now converted to
use atomic operations. [GL #1475]
--- 9.16.5 released ---
5458. [bug] Prevent a theoretically possible NULL dereference caused
by a data race between zone_maintenance() and
dns_zone_setview_helper(). [GL #1627]
5455. [bug] named could crash when cleaning dead nodes in
lib/dns/rbtdb.c that were being reused. [GL #1968]
5454. [bug] Address a startup crash that occurred when the server
was under load and the root zone had not yet been
loaded. [GL #1862]
5453. [bug] named crashed on shutdown when a new rndc connection was
received during shutdown. [GL #1747]
5452. [bug] The "blackhole" ACL was accidentally disabled for client
queries. [GL #1936]
5451. [func] Add 'rndc dnssec -status' command. [GL #1612]
5449. [bug] Fix a socket shutdown race in netmgr udp. [GL #1938]
5448. [bug] Fix a race condition in isc__nm_tcpdns_send().
[GL #1937]
5447. [bug] IPv6 addresses ending in "::" could break YAML
parsing. A "0" is now appended to such addresses
in YAML output from dig, mdig, delv, and dnstap-read.
[GL #1952]
5446. [bug] The validator could fail to accept a properly signed
RRset if an unsupported algorithm appeared earlier in
the DNSKEY RRset than a supported algorithm. It could
also stop if it detected a malformed public key.
[GL #1689]
